Liquid-phase hydrogenation of benzene ring in gasoline fractions of Atyrau Oil Refinery LLP (Kazakhstan) was studied.Mono-and bimetallic catalysts on the basis of platinum metals on various carriers were synthesized.It was succeeded to reduce aromatic compounds content (totally) for "hydrogenate" fraction to 0.6-4.64 % (in initial gasoline -11.2 %), and also to completely exclude the content of benzene from final sample or to reduce its quantity to 0.06 % (in the initial sample -2.54 %).For the fraction "stable catalysate" benzene content was reduced to 0.15 wt.% (in the initial sample -5.17 % wt.), benzene conversion -97 %.For the fraction "hydrogenate" aromatic compounds content was decreased from 13.70 to 2.26 wt.%.For the "stable catalysate" an amount of aromatic compounds was reduced from 51.5 to 22.96 wt.%.At catalytic hydrodearomatization of the gasoline fractions octane number was not reduced.
